Yups, Saya pakai Trezor one bisa menyimpan banyak macam cryptocurrency : ETH, LTC, Zcash, Ripple, dll.
Tapi, Kita bisa upgrade firmware Hanya khusus Bitcoin, https://wiki.trezor.io/Bitcoin_firmware
trezor model one firmware version 1.8.3 https://wiki.trezor.io/Firmware_changelog

Dan, jika mau trezornya dipakai buat banyak cryptocurrency, cukup pakai yang firmware versi 1.8.2
